Figured someone on the list would have an opinion on a very lightweight feature-poor IMAP client. It doesn't need to do much else but access a single IMAP account and be able to forward emails as attachments. Search would be good, but not required. Searching for queueIDs in the Received header would be fantastic.
Primary considerations are fast and as light on memory use as possible and usable from a Mac (command-line is fine). I know mutt can do IMAP but I don't think it can forward messages as attachments though I am probably wrong. Windows 10 might be useful, but not required. -- Apple broke AppleScripting signatures in Mail.app, so no random signatures.
